Description

FIELD OF THE INVENTION The present invention relates to a method of constructing a high-rise building, for example a high-rise building.

2. Description of the Related Art Conventionally, in the case of constructing a high-rise building, a steel frame, an exterior material, and the like are sequentially carried upward by a tower crane and assembled by a skilled worker.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention By the way, according to the above construction method, since the assembly is performed manually, there is a problem that the work cannot be performed on a windy and rainy day, which affects the construction period. . Further, there is a problem that even if the work can be performed, there is a danger.

Then, this invention aims at providing the construction method of the high-rise building which can eliminate the said subject.

Means for Solving the Problems In order to solve the above problems, the method for constructing a high-rise building of the present invention, when sequentially assembling a high-rise building from the bottom to the top, at the upper end of the structure under construction, This is a method of supporting a temporary structure having at least its upper surface and all side surfaces covered with a plate, and assembling a steel frame, an exterior material, and the like using an overhead crane and an assembly robot arranged in this temporary structure.

Action According to the above construction method, since the high-rise building is assembled in the temporary structure covered with the plate, the construction delay and work risk due to wind and rain are eliminated, and the overhead traveling crane and the work robot are used. By using such as, it is possible to improve the assembly accuracy and shorten the construction period.

Embodiment One embodiment of the present invention will be described below with reference to FIGS. 1 to 6.

First, a temporary structure used in the present construction method will be described with reference to FIGS. 1 to 4.

That is, the temporary structure 1 includes a side frame 2 that is larger than an outer peripheral surface of a high-rise building (hereinafter, simply referred to as a building) A, which is a building, by a predetermined width, and an entire upper surface of the side frame 2. An upper frame body 3 which is arranged and supported over the entire length, and a plate body which covers the entire outer peripheral surfaces of these frame bodies 2 and 3 (for example, a thin steel plate)
And a work frame 5 composed of 4 and this work frame 5.
And a raising device 6 for raising the above with respect to the building A. A plate body 4 is also provided on the lower surface of the side frame body 2 in order to prevent the temporary structure 1 from dropping. In addition, as shown in FIG.
A lifting cylinder device (for example, a hydraulic cylinder) 7 suspended at a plurality of places around the lower end portion 2a of the side frame body 2, and a support member 8 supported by the tip of a rod 7a of the lifting cylinder device 7. An upper lock cylinder device provided at the lower end portion 2a of the side frame body 2 for moving the upper support pin 9 into and out of the insertion hole 10 of the building, that is, the structure B side under construction.
11 (for example, a hydraulic cylinder) and a lower lock cylinder device 13 (for example, a hydraulic cylinder) that is provided on the support member 8 and that allows the lower support pin 12 to move in and out of the insertion hole 10 on the structure B side. Has been done. In addition, in FIG.
Reference numeral 14 is a guide roller provided on the work frame 5 side and the support member 8 side.

Therefore, when raising the work frame 5 with respect to the structure B, first with the upper and lower support pins 9 and 12 inserted into the insertion holes 10 on the structure B side, first pull out the upper support pin 9. Then, after extending the rod 7a of the raising cylinder device 7 and raising the work frame 5 with respect to the structure B,
The upper support pin 9 may be inserted into the upper insertion hole 10 on the structure B side. Then, in order to raise again, after pulling out the lower support pin 12 from the insertion hole 10, the rod 7a of the lifting cylinder 7 is contracted to insert the lower support pin 12 into the upper insertion hole 10, and the upper support again. It is sufficient to pull out the pin 9 and extend the rod 7a of the lifting cylinder 7. By repeating this procedure, the work frame body 5, that is, the entire temporary structure 1 can be raised according to the assembly of the building A.

Further, as shown in FIG. 2, a plurality of overhead traveling cranes 15 are arranged inside the work frame 5, that is, in the upper frame 3, and the side frame 2 surrounds the building A. A plurality of work robots 16 are arranged so that they can run freely along. That is, the work robot 16 has a fourth
As shown in the figure, a traveling carriage 19 having traveling wheels 18 guided by a pair of upper and lower traveling rails 17 laid on the step portion 2b of the side frame body 2, and a traveling carriage 19 provided on the traveling carriage 19 and various The robot main body 21 has a manipulator 20 for work.

Next, a building construction method will be described.

First, as shown in Fig. 5, after building a building foundation C,
A pedestal 22 is provided around it. Next, the work frame 5 is supported on the pedestal 22. That is, the lower block body 5A, which is the lower portion of the side frame body 2 in which the work frame body 5 is formed into a block, is assembled on the pedestal 22 using a truck crane or the like. Next, the intermediate block body, which is the upper portion of the side frame body 2 and the peripheral portion of the upper frame body 3, which are also formed into blocks.
5B is assembled using a truck crane or the like, and the upper block body 5C, which is the central portion of the upper frame body 3, is similarly assembled. Then, the overhead traveling crane 15 and the work robot 16 are arranged at the time of or after assembling these.
In addition, a dismantling crane for dismantling the work frame 5 is installed in a suitable position of the work frame 5, for example, near the end of the upper frame 3 in a disassembled state, and the dismantling crane is also installed. A small crane for unloading the ship to the ground is also installed on the tower. Next, on the foundation C, the overhead traveling crane 15 and the work robot 16 are used to assemble steel frames, floor materials, exterior materials, and the like. Then, after the assembly of a predetermined height, for example, the assembly of one layer is completed, the elevating device 6 is used to elevate the entire work frame body 5, and the same operation as above is repeated again,
Assemble building A high one by one. The quality material is carried in during assembly through an access hole provided in the structure B during assembly. When the uppermost layer is assembled, as shown in FIG. 6, the dismantling crane 23 is assembled on the upper surface of the work frame 5, and the dismantling crane 23 disassembles the upper block body 5C of the upper frame body 3. And drop it on the ground. Then, the dismantling crane 23 is once disassembled by a small crane (not shown) that is pre-mounted on the tower, and the dismantling crane 23 is lowered onto the roof of the building A. It is sufficient to unload it to the ground, finally dismantle the small crane, and unload it to the ground by the elevator already installed in building A. Incidentally, during the assembly of the building A, as shown in FIG. 1, columns 24 for supporting the temporary structure 1 on the side of the building A are provided, and also when the temporary structure 1 is dismantled, as shown in FIG. Thus, the dismantling reinforcement member 25 is provided.

As described above, since the assembly work of the building A is performed inside the work frame 5, the construction period delay due to wind and rain and the risk of work are eliminated, and the overhead traveling crane 15 and the work robot 16 are used. Therefore, the assembling accuracy can be improved and the construction period can be shortened.

By the way, although the cylinder device is used as the lifting device in the above-described embodiment, for example, a rack and pinion mechanism may be used.

As described above, according to the construction method of the present invention, since the assembly of the high-rise building is performed in the temporary structure covered with the plate body, the delay of the construction period due to wind and rain and the risk of the work are eliminated, and Since an overhead traveling crane and a work robot are used, the assembly accuracy can be improved and the construction period can be shortened.
